Yep, I'm running a campaign right now and I did switch from trucks. My current battle has my tracks parked in the rear while the infantry is deployed up front. The battle is a delay with high visibility and nothing to hide behind. I figure they make a handy reserve once the enemy tanks are all basically destroyed.

Generally, the tracks park on defends and delays, meeting engagements and advances are terrain dependent and my troops are always mounted during assaults. During assaults, support troops act as my breach force and my whole core moves through the hole and into the rear.
